Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's.

Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

static void
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions.

More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

{
_gtk_text_btree_remove_view (_gtk_text_buffer_get_btree (layout->buffer),
update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

if (layout->default_style)
gtk_text_attributes_unref (layout->default_style);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

PangoContext *rtl_context)
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/.

(Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

(Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

gtk_text_layout_free_line_data (GtkTextLayout *layout,

GtkTextLineData *line_data)
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

GTK_TEXT_LAYOUT_GET_CLASS (layout)->free_line_data (layout, line, line_data);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

GtkTextLineData*
gtk_text_layout_wrap (GtkTextLayout *layout,

GtkTextLineData *line_data)
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.)

Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

/* -1 since bottom_y is one past */
update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

last_btree_line =
_gtk_text_btree_find_line_by_y (_gtk_text_buffer_get_btree (layout->buffer),

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

if (!last_btree_line)
update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case.

More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C.

(Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Move GdkColor args to GTK_TYPE_POINTER also. * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): temporarily use GTK_TYPE_POINTER for signal signatures as a hack-around * gtk/gtk-boxed.defs: Add boxed types for PangoFontDescription and PangoTabArray * gtk/gtktextlayout.c (line_display_iter_to_index): make static (line_display_index_to_iter): make static * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): fix marshaller to marshal a string not a boxed * gtk/gtkmarshal.list: add marshaller for GtkTextBuffer:insert_text * gtk/testtext.c (fill_file_buffer): don't use g_utf8_next_char since the UTF-8 isn't validated yet * gtk/gtktextsegment.c (char_segment_check_func): don't require lines to end in '\n' * gtk/gtktextview.c (gtk_text_view_move_cursor): update to use forward_to_delimiters, and grapheme boundaries (gtk_text_view_delete_from_cursor): properly handle non-newline delimiters, and grapheme boundaries * gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): rename to gtk_text_iter_forward_to_delimiters, and make it work properly if empty lines end with a character other than '\n' * gtk/gtktextiter.h, gtk/gtktextiter.c: Add movement by cursor position

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Move GdkColor args to GTK_TYPE_POINTER also. * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): temporarily use GTK_TYPE_POINTER for signal signatures as a hack-around * gtk/gtk-boxed.defs: Add boxed types for PangoFontDescription and PangoTabArray * gtk/gtktextlayout.c (line_display_iter_to_index): make static (line_display_index_to_iter): make static * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): fix marshaller to marshal a string not a boxed * gtk/gtkmarshal.list: add marshaller for GtkTextBuffer:insert_text * gtk/testtext.c (fill_file_buffer): don't use g_utf8_next_char since the UTF-8 isn't validated yet * gtk/gtktextsegment.c (char_segment_check_func): don't require lines to end in '\n' * gtk/gtktextview.c (gtk_text_view_move_cursor): update to use forward_to_delimiters, and grapheme boundaries (gtk_text_view_delete_from_cursor): properly handle non-newline delimiters, and grapheme boundaries * gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): rename to gtk_text_iter_forward_to_delimiters, and make it work properly if empty lines end with a character other than '\n' * gtk/gtktextiter.h, gtk/gtktextiter.c: Add movement by cursor position

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public.

More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Move GdkColor args to GTK_TYPE_POINTER also. * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): temporarily use GTK_TYPE_POINTER for signal signatures as a hack-around * gtk/gtk-boxed.defs: Add boxed types for PangoFontDescription and PangoTabArray * gtk/gtktextlayout.c (line_display_iter_to_index): make static (line_display_index_to_iter): make static * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): fix marshaller to marshal a string not a boxed * gtk/gtkmarshal.list: add marshaller for GtkTextBuffer:insert_text * gtk/testtext.c (fill_file_buffer): don't use g_utf8_next_char since the UTF-8 isn't validated yet * gtk/gtktextsegment.c (char_segment_check_func): don't require lines to end in '\n' * gtk/gtktextview.c (gtk_text_view_move_cursor): update to use forward_to_delimiters, and grapheme boundaries (gtk_text_view_delete_from_cursor): properly handle non-newline delimiters, and grapheme boundaries * gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): rename to gtk_text_iter_forward_to_delimiters, and make it work properly if empty lines end with a character other than '\n' * gtk/gtktextiter.h, gtk/gtktextiter.c: Add movement by cursor position

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

if (tags == NULL || tags->len == 0)
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/.

Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program.

(Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

layout->one_style_cache = style;
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Add built marshaller files to support GdkPixbufLoader signals 2001-01-22 Havoc Pennington <hp@redhat.com> * Makefile.am: Add built marshaller files to support GdkPixbufLoader signals * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in module location, rather than acting as a fallback, because we are using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it. * gdk-pixbuf.h: include gdk-pixbuf-loader.h * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here from gtk, and add error to close(), because stop_load may do parsing of the image. * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file * io-*.c: make individual operations static, and add fill_vtable functions which are exported. Fix the collection of type warnings that surfaced, including a number of functions that didn't properly take a GError and some that weren't const-correct. Involved adding error handling for a few loaders. * gdk-pixbuf-io.h: Add error reporting to stop_load function * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up a function that fills in the GdkPixbufModule vtable, instead of looking up all the image functions individually; this means we can get type safety within modules for the loader functions. Also it means you don't have to keep the statically compiled and GModule versions in sync. * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init() * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init() * gdk-pixbuf.h: nuke gdk_pixbuf_init() * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init () here * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type): g_type_init() here 2001-01-22 Havoc Pennington <hp@redhat.com> * demos/testanimation.c: fix to reflect gdk-pixbuf changes * demos/testpixbuf.c: fix to reflect gdk-pixbuf changes * gtk/gdk-pixbuf-loader.c, gtk/gdk-pixbuf-loader.h: Remove, move back to gdk-pixbuf * gtk/gtktextiter.c, gtk/gtktextiter.h: add sentence equivalents to all the word functions * gtk/gtktextview.c (gtk_text_view_start_cursor_blink): return before doing anything on NULL layout or if we don't have the focus * gtk/testtext.c (fill_example_buffer): "justification" * gtk/gtktexttag.h, gtk/gtktexttag.c: change the tag attribute to be called "justification" not "justify" * demos/gtk-demo/textview.c (create_tags): "justification" * gtk/gtktextlayout.c (set_para_values): Handle char-wise wrapping

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

(Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.)

(We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Add built marshaller files to support GdkPixbufLoader signals 2001-01-22 Havoc Pennington <hp@redhat.com> * Makefile.am: Add built marshaller files to support GdkPixbufLoader signals * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in module location, rather than acting as a fallback, because we are using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it. * gdk-pixbuf.h: include gdk-pixbuf-loader.h * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here from gtk, and add error to close(), because stop_load may do parsing of the image. * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file * io-*.c: make individual operations static, and add fill_vtable functions which are exported. Fix the collection of type warnings that surfaced, including a number of functions that didn't properly take a GError and some that weren't const-correct. Involved adding error handling for a few loaders. * gdk-pixbuf-io.h: Add error reporting to stop_load function * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up a function that fills in the GdkPixbufModule vtable, instead of looking up all the image functions individually; this means we can get type safety within modules for the loader functions. Also it means you don't have to keep the statically compiled and GModule versions in sync. * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init() * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init() * gdk-pixbuf.h: nuke gdk_pixbuf_init() * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init () here * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type): g_type_init() here 2001-01-22 Havoc Pennington <hp@redhat.com> * demos/testanimation.c: fix to reflect gdk-pixbuf changes * demos/testpixbuf.c: fix to reflect gdk-pixbuf changes * gtk/gdk-pixbuf-loader.c, gtk/gdk-pixbuf-loader.h: Remove, move back to gdk-pixbuf * gtk/gtktextiter.c, gtk/gtktextiter.h: add sentence equivalents to all the word functions * gtk/gtktextview.c (gtk_text_view_start_cursor_blink): return before doing anything on NULL layout or if we don't have the focus * gtk/testtext.c (fill_example_buffer): "justification" * gtk/gtktexttag.h, gtk/gtktexttag.c: change the tag attribute to be called "justification" not "justify" * demos/gtk-demo/textview.c (create_tags): "justification" * gtk/gtktextlayout.c (set_para_values): Handle char-wise wrapping

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Add built marshaller files to support GdkPixbufLoader signals 2001-01-22 Havoc Pennington <hp@redhat.com> * Makefile.am: Add built marshaller files to support GdkPixbufLoader signals * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in module location, rather than acting as a fallback, because we are using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it. * gdk-pixbuf.h: include gdk-pixbuf-loader.h * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here from gtk, and add error to close(), because stop_load may do parsing of the image. * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file * io-*.c: make individual operations static, and add fill_vtable functions which are exported. Fix the collection of type warnings that surfaced, including a number of functions that didn't properly take a GError and some that weren't const-correct. Involved adding error handling for a few loaders. * gdk-pixbuf-io.h: Add error reporting to stop_load function * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up a function that fills in the GdkPixbufModule vtable, instead of looking up all the image functions individually; this means we can get type safety within modules for the loader functions. Also it means you don't have to keep the statically compiled and GModule versions in sync. * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init() * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init() * gdk-pixbuf.h: nuke gdk_pixbuf_init() * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init () here * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type): g_type_init() here 2001-01-22 Havoc Pennington <hp@redhat.com> * demos/testanimation.c: fix to reflect gdk-pixbuf changes * demos/testpixbuf.c: fix to reflect gdk-pixbuf changes * gtk/gdk-pixbuf-loader.c, gtk/gdk-pixbuf-loader.h: Remove, move back to gdk-pixbuf * gtk/gtktextiter.c, gtk/gtktextiter.h: add sentence equivalents to all the word functions * gtk/gtktextview.c (gtk_text_view_start_cursor_blink): return before doing anything on NULL layout or if we don't have the focus * gtk/testtext.c (fill_example_buffer): "justification" * gtk/gtktexttag.h, gtk/gtktexttag.c: change the tag attribute to be called "justification" not "justify" * demos/gtk-demo/textview.c (create_tags): "justification" * gtk/gtktextlayout.c (set_para_values): Handle char-wise wrapping

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.)

Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Add GdkPangoRenderer, a subclass of PangoRenderer targeting GDK drawables. Sat Nov 20 15:13:51 2004 Owen Taylor <otaylor@redhat.com> * gdk/gdkpango.[ch]: Add GdkPangoRenderer, a subclass of PangoRenderer targeting GDK drawables. Use to implement the old gdk_draw_layout() and friends. * gdk/gdkdraw.c gdk/gdkdrawable.h gdk/gdkwindow.c gdk/gdkpixmap.c: Add gdk_draw_glyphs_transformed() gdk_draw_trapezoids() and the corresponding members of GdkDrawableClass.

Leave line_display->shaped_objects around for backwords compatibility. * gdk/gdkpango.[ch] (gdk_pango_context_set_colormap): Describe as deprecated, remove implementation. * gtk/gtkwidget.c (gtk_widget_create_pango_context): Remove call to gdk_pango_context_set_colormap. * demos/gtk-demo/Makefile.am demos/gtk-demo/rotated_text.c: Add a demo showing drawing rotated text. * tests/testgtk.c: Add a rotated-label test, and also a rotated drawing test (differs from demos/gtk-demo/rotated_text by also using a tile)

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.)

Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

/* Hide insertion cursor when we have a selection or the layout
* user has hidden the cursor.
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

(Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

GtkTextLayoutPrivate *priv = GTK_TEXT_LAYOUT_GET_PRIVATE (layout);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Make parent_class static. Sun Nov 5 04:24:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcellrenderertextpixbuf.c: Make parent_class static. Tue Sep 19 10:54:22 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext*.[ch] gtk/gtkimmulticontext.[ch] gtk/gtktextlayout.[ch] gtk/gtktextview.c gtk/gtkentry.c: Add support for positioning the cursor within the preedit string. Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

display->insert_index = -1;
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

release_style (layout, style);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

remove unused call to get_last_line() 2000-12-14 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (_gtk_text_btree_validate_line): remove unused call to get_last_line() * gtk/gtkobject.c (gtk_object_add_arg_type): add G_TYPE_POINTER here until boxed is working (and maybe after that - we should really not gratuitously break old code) * gtk/gtktexttag.c (gtk_text_tag_class_init): add commented-out specific types for font_desc and tabs args, move them to GTK_TYPE_POINTER for now, waiting on g_param_spec_boxed() to get fixed. Move GdkColor args to GTK_TYPE_POINTER also. * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): temporarily use GTK_TYPE_POINTER for signal signatures as a hack-around * gtk/gtk-boxed.defs: Add boxed types for PangoFontDescription and PangoTabArray * gtk/gtktextlayout.c (line_display_iter_to_index): make static (line_display_index_to_iter): make static * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): fix marshaller to marshal a string not a boxed * gtk/gtkmarshal.list: add marshaller for GtkTextBuffer:insert_text * gtk/testtext.c (fill_file_buffer): don't use g_utf8_next_char since the UTF-8 isn't validated yet * gtk/gtktextsegment.c (char_segment_check_func): don't require lines to end in '\n' * gtk/gtktextview.c (gtk_text_view_move_cursor): update to use forward_to_delimiters, and grapheme boundaries (gtk_text_view_delete_from_cursor): properly handle non-newline delimiters, and grapheme boundaries * gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): rename to gtk_text_iter_forward_to_delimiters, and make it work properly if empty lines end with a character other than '\n' * gtk/gtktextiter.h, gtk/gtktextiter.c: Add movement by cursor position

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public.

(No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.)

Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1.

(No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

g_return_if_fail (GTK_IS_TEXT_LAYOUT (layout));
g_return_if_fail (target_iter != NULL);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public.

Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.)

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/.

Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program.

(Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.)

(Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

* gtk_text_layout_get_cursor_locations:
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

/**
* gtk_text_layout_get_line_yrange:
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

display = gtk_text_layout_get_line_display (layout, line, FALSE);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

rect->y = _gtk_text_btree_find_line_top (tree, line, layout);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public.

Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.
2000-06-02 03:14:07 +00:00
Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

pango_layout_iter_free (layout_iter);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

(gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

pango_layout_iter_free (layout_iter);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

else
update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function
2000-07-25 23:59:38 +00:00
gtk_text_buffer_get_iter_at_offset (layout->buffer, iter, 0);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.)

Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.)

(Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display.

Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

* gtk_text_layout_move_iter_to_previous_line:
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

gtk_text_layout_move_iter_to_previous_line (GtkTextLayout *layout,
GtkTextIter *iter)
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

voc Pennington <hp@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it. (gtk_widget_modify_color_component): call gtk_widget_modify_style() so the rc style will get copied. (gtk_widget_modify_font): ditto * gtk/gtkrc.c: make a couple variables static * gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide help button by default, since it does nothing * gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool around with UI * gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify so we can have tooltips * gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we can have tooltips * gdk/gdkimage.h: mark gdk_image_new_bitmap with GDK_ENABLE_BROKEN, because its memory behavior is completely hosed. * gtk/gtknotebook.c: remove key press handler, replace with binding set, add numeric keypad support * gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete * gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms * gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in addition to plain Delete * gtk/gtktextview.c (gtk_text_view_key_press_event): accept GDK_KP_Enter in addition to GDK_Return * gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to activate on entry instead of key press (gtk_font_selection_on_clist_key_press): get rid of this signal handler, not needed with new font sel. * gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a no-longer-needed emit_stop_by_name(), just return TRUE * gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings cruft, this widget is no longer focusable. * gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c, gtk/gtkhscale.c: Get rid of trough_keys virtual function, add move_slider action signal, add binding set for vscale/hscale, in the process support numeric keypad * gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings; make GDK_Return and GDK_KP_Enter activate the entry via binding set, instead of hardcoded.

Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode.

Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

voc Pennington <hp@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it. (gtk_widget_modify_color_component): call gtk_widget_modify_style() so the rc style will get copied. (gtk_widget_modify_font): ditto * gtk/gtkrc.c: make a couple variables static * gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide help button by default, since it does nothing * gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool around with UI * gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify so we can have tooltips * gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we can have tooltips * gdk/gdkimage.h: mark gdk_image_new_bitmap with GDK_ENABLE_BROKEN, because its memory behavior is completely hosed. * gtk/gtknotebook.c: remove key press handler, replace with binding set, add numeric keypad support * gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete * gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms * gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in addition to plain Delete * gtk/gtktextview.c (gtk_text_view_key_press_event): accept GDK_KP_Enter in addition to GDK_Return * gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to activate on entry instead of key press (gtk_font_selection_on_clist_key_press): get rid of this signal handler, not needed with new font sel. * gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a no-longer-needed emit_stop_by_name(), just return TRUE * gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings cruft, this widget is no longer focusable. * gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c, gtk/gtkhscale.c: Get rid of trough_keys virtual function, add move_slider action signal, add binding set for vscale/hscale, in the process support numeric keypad * gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings; make GDK_Return and GDK_KP_Enter activate the entry via binding set, instead of hardcoded.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

layout_line = tmp_list->data;
voc Pennington <hp@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it. (gtk_widget_modify_color_component): call gtk_widget_modify_style() so the rc style will get copied. (gtk_widget_modify_font): ditto * gtk/gtkrc.c: make a couple variables static * gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide help button by default, since it does nothing * gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool around with UI * gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify so we can have tooltips * gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we can have tooltips * gdk/gdkimage.h: mark gdk_image_new_bitmap with GDK_ENABLE_BROKEN, because its memory behavior is completely hosed. * gtk/gtknotebook.c: remove key press handler, replace with binding set, add numeric keypad support * gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete * gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms * gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in addition to plain Delete * gtk/gtktextview.c (gtk_text_view_key_press_event): accept GDK_KP_Enter in addition to GDK_Return * gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to activate on entry instead of key press (gtk_font_selection_on_clist_key_press): get rid of this signal handler, not needed with new font sel. * gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a no-longer-needed emit_stop_by_name(), just return TRUE * gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings cruft, this widget is no longer focusable. * gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c, gtk/gtkhscale.c: Get rid of trough_keys virtual function, add move_slider action signal, add binding set for vscale/hscale, in the process support numeric keypad * gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings; make GDK_Return and GDK_KP_Enter activate the entry via binding set, instead of hardcoded.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

{
voc Pennington <hp@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it. (gtk_widget_modify_color_component): call gtk_widget_modify_style() so the rc style will get copied. (gtk_widget_modify_font): ditto * gtk/gtkrc.c: make a couple variables static * gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide help button by default, since it does nothing * gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool around with UI * gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify so we can have tooltips * gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we can have tooltips * gdk/gdkimage.h: mark gdk_image_new_bitmap with GDK_ENABLE_BROKEN, because its memory behavior is completely hosed. * gtk/gtknotebook.c: remove key press handler, replace with binding set, add numeric keypad support * gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete * gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms * gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in addition to plain Delete * gtk/gtktextview.c (gtk_text_view_key_press_event): accept GDK_KP_Enter in addition to GDK_Return * gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to activate on entry instead of key press (gtk_font_selection_on_clist_key_press): get rid of this signal handler, not needed with new font sel. * gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a no-longer-needed emit_stop_by_name(), just return TRUE * gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings cruft, this widget is no longer focusable. * gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c, gtk/gtkhscale.c: Get rid of trough_keys virtual function, add move_slider action signal, add binding set for vscale/hscale, in the process support numeric keypad * gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings; make GDK_Return and GDK_KP_Enter activate the entry via binding set, instead of hardcoded.

GtkTextLine *prev_line;
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

voc Pennington <hp@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C.

(Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

gboolean
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

gtk_text_layout_move_iter_to_next_line (GtkTextLayout *layout,
GtkTextIter *iter)
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

voc Pennington <hp@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it. (gtk_widget_modify_color_component): call gtk_widget_modify_style() so the rc style will get copied. (gtk_widget_modify_font): ditto * gtk/gtkrc.c: make a couple variables static * gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide help button by default, since it does nothing * gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool around with UI * gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify so we can have tooltips * gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we can have tooltips * gdk/gdkimage.h: mark gdk_image_new_bitmap with GDK_ENABLE_BROKEN, because its memory behavior is completely hosed. * gtk/gtknotebook.c: remove key press handler, replace with binding set, add numeric keypad support * gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete * gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms * gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in addition to plain Delete * gtk/gtktextview.c (gtk_text_view_key_press_event): accept GDK_KP_Enter in addition to GDK_Return * gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to activate on entry instead of key press (gtk_font_selection_on_clist_key_press): get rid of this signal handler, not needed with new font sel. * gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a no-longer-needed emit_stop_by_name(), just return TRUE * gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings cruft, this widget is no longer focusable. * gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c, gtk/gtkhscale.c: Get rid of trough_keys virtual function, add move_slider action signal, add binding set for vscale/hscale, in the process support numeric keypad * gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings; make GDK_Return and GDK_KP_Enter activate the entry via binding set, instead of hardcoded.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

voc Pennington <hp@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_previous_line): (gtk_text_layout_move_iter_to_next_line): fix these two for invisible text, lots of other stuff still hosed. * gtk/gtkcolorsel.c (gtk_color_selection_set_change_palette_hook): new function, replaces the get/set palette stuff. This function is intended for use by libgnomeui which should set the hook to a thing which sets the palette in GConf, and we need the GConf-to-xsettings proxy which will result in the change being propagated back to the GTK app. * gtk/gtkaccelgroup.c (gtk_accel_group_add): add note to warning about unusable signals that it may be because the signal has parameters. * gtk/gtkwidget.c (gtk_widget_modify_style): always copy the style, otherwise gtkrc.c won't know to create a new GtkStyle for it. (gtk_widget_modify_color_component): call gtk_widget_modify_style() so the rc style will get copied. (gtk_widget_modify_font): ditto * gtk/gtkrc.c: make a couple variables static * gtk/gtkcolorseldialog.c (gtk_color_selection_dialog_init): hide help button by default, since it does nothing * gtk/gtkcolorsel.c: add tooltips, work on key navigation, fool around with UI * gtk/gtkentry.c (gtk_entry_realize): request enter/leave notify so we can have tooltips * gtk/gtkhsv.c (gtk_hsv_realize): request enter/leave notify so we can have tooltips * gdk/gdkimage.h: mark gdk_image_new_bitmap with GDK_ENABLE_BROKEN, because its memory behavior is completely hosed. * gtk/gtknotebook.c: remove key press handler, replace with binding set, add numeric keypad support * gtk/gtktextview.c (gtk_text_view_class_init): accept KP_Delete * gtk/gtktext.c (gtk_text_key_press): add a bunch of KP keysyms * gtk/gtkentry.c (gtk_entry_class_init): accept GDK_KP_Delete in addition to plain Delete * gtk/gtktextview.c (gtk_text_view_key_press_event): accept GDK_KP_Enter in addition to GDK_Return * gtk/gtkfontsel.c (gtk_font_selection_size_key_press): connect to activate on entry instead of key press (gtk_font_selection_on_clist_key_press): get rid of this signal handler, not needed with new font sel. * gtk/gtkfilesel.c (gtk_file_selection_key_press): remove a no-longer-needed emit_stop_by_name(), just return TRUE * gtk/gtkhscrollbar.c, gtk/gtkvscrollbar.c: remove keybindings cruft, this widget is no longer focusable. * gtk/gtkrange.h, gtk/gtkrange.c, gtk/gtkvscale.c, gtk/gtkhscale.c: Get rid of trough_keys virtual function, add move_slider action signal, add binding set for vscale/hscale, in the process support numeric keypad * gtk/gtkentry.c (gtk_entry_class_init): Add keypad bindings; make GDK_Return and GDK_KP_Enter activate the entry via binding set, instead of hardcoded.

next:
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Add C-d, M-d, C-v bindings, change Home, End to move to beginning/end of line, Add C-Home C-End to move to beginning/end of buffer. Change ::cut_text to ::cut_clipboard, etc; combine ::scroll_text into ::move; use new GtkSelectionData functions to simplify DND text handling. * gtk/gtkenums.h gtk/gtktextview.h: Move movement, deletion enumerations here, rename enumeration values to be consistently plural. * gtk/gtktextbuffer.c: Use new clipboard interfaces for cut/copy/paste and primary selection. * gtk/gtktextbuffer.[ch]: Remove excess time and 'interactive' arguments from cut/copy/paste; rename cut to cut_clipboard, etc; remove gtk_text_buffer_get_clipboard_contents(). * gtk/gtktextlayout.[ch]: Add gtk_text_layout_move_iter_to_line_end() to move the iter to line ends. * gtk/gtkselection.[ch] (gtk_selection_data_set/get_text): Functions to set or get a UTF-8 string on the selection data. * gtk/gtkclipboard.[ch]: New, simplified selection handling interfaces. * gtk/gtkinvisible.c (gtk_invisible_new): Realize newly created widgets - one of these is useless if we don't. * gtk/gtkselection.[ch] (gtk_selection_clear_targets): Export a public function clear all targets registered for the widget. * gtk/gtkselection.c (gtk_selection_owner_set) docs/Changes-2.0.txt: Never call gtk_widget_realize() - that was just asking for bizarre side-effects. * gtk/gtkselection.c (gtk_selection_owner_set): Call gdk_selection_owner_set even if the widget is the same so that we reliably update the timestamp on the server. * gdk/x11/gdkevents-x11.c gdk/x11/gdkx.h: Add a gdk_x11_get_server_time() function. * gdk/x11/gdkevents-x11.c gdk/x11/gdkprivate-x11.h gdk/x11/gdkselection-x11.c gdk/x11/gdkwindow-x11.h: Add some tricky filtering on serial numbers for selection clear events to fix up long-standard race condition FIXME's in gtkselection.c. * gdk/gdkproperty.h gdk/x11/gdkselection-x11.h: Add routines to convert from utf8 to compound text or STRING and from a text property to UTF-8. * gtk/gtkmain.[ch] (gtk_get_current_event_time): Add a convenience function gdk_get_current_event_time(). * gtk/gtkselection.c (gtk_selection_data_copy/free): Copy and free selection_data->data properly

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Adapt to uscore-ification of gtktextiterprivate 2001-01-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c: Adapt to uscore-ification of gtktextiterprivate * gtk/gtktextdisplay.c (gtk_text_layout_draw): remove use of private functions; remove inclusion of private headers. * gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_line): Add this function, so we don't need private functions in gtktextdisplay.c * gtk/gtktextiterprivate.h: underscore-ification * gtk/gtkwidget.c: Clean up a bunch of docs that said "INTERNAL" to instead say "only useful to implement widgets" * gtk/gtkenums.h (GtkMovementStep): Rename GTK_MOVEMENT_CHARS, GTK_MOVEMENT_POSITIONS to GTK_MOVEMENT_LOGICAL_POSITIONS, GTK_MOVEMENT_VISUAL_POSITIONS. Resolves bug 40249. * gdk/x11/gdkwindow-x11.c (gdk_window_impl_x11_set_colormap): This function was completely broken * gtk/testtext.c (line_numbers_expose): use gtk_paint_layout * gtk/gtkvscale.c (gtk_vscale_draw_value): use gtk_paint_layout * gtk/gtkvruler.c (gtk_vruler_draw_ticks): use gtk_paint_layout * gtk/gtklabel.c (gtk_label_expose): use gtk_paint_layout * gtk/gtkhscale.c (gtk_hscale_draw_value): use gtk_paint_layout * gtk/gtkhruler.c (gtk_hruler_draw_ticks): use gtk_paint_layout * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render): use gtk_paint_layout * gtk/gtkaccellabel.c (gtk_accel_label_expose_event): use gtk_paint_layout * gtk/gtkstyle.h: Add draw/paint expander to draw tree expanders. Progress on bug 40103. Add draw_layout to draw a PangoLayout. (struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Make parent_class static. Sun Nov 5 04:24:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcellrenderertextpixbuf.c: Make parent_class static. Tue Sep 19 10:54:22 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext*.[ch] gtk/gtkimmulticontext.[ch] gtk/gtktextlayout.[ch] gtk/gtktextview.c gtk/gtkentry.c: Add support for positioning the cursor within the preedit string. Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Free the filename of the module file. 2000-11-13 Havoc Pennington <hp@redhat.com> * gtk/gtkimmodule.c (gtk_im_module_init): Free the filename of the module file. * gtk/gtktexttag.c (gtk_text_attributes_copy): fix memory leak of dest->language * gtk/testtext.c: Test pixels above/below/inside paragraphs settings * gtk/gtktextview.c: Implement object args and setters/getters for all the aspects of the GtkTextAttributes that are not set from GtkWidget attributes. This is spacing, justification, margins, etc. (gtk_text_view_set_arg) (gtk_text_view_get_arg): implement get/set for editable, wrap mode args (gtk_text_view_class_init): Add args for justify, left_margin, right_margin, indent, and tabs * gtk/gtktextlayout.c (set_para_values): fix to display indent attribute properly * gtk/gtktexttag.c: Remove left_wrapped_line_margin attribute, replace with indent attribute * gtk/gtktextlayout.c (set_para_values): multiply indent by PANGO_SCALE * gtk/gtktextdisplay.c (render_para): Use PangoLayoutIter, rearranging code to do that (gtk_text_layout_draw): Pass in the y for the whole LineDisplay, i.e. don't subtract the top_margin first, just to keep all margin-futzing in one place. * gdk/gdkpango.c (gdk_draw_layout): Use PangoLayoutIter * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Remove special case of last line, Pango now handles this itself. (gtk_text_layout_get_iter_at_pixel): Fix incorrect clamp of the Y coordinate (gtk_text_layout_move_iter_to_x): port to use PangoLayoutIter (find_display_line_above): wasn't moving the byte index as it iterated over lines, so always returned byte 0. Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

PangoLayoutLine *layout_line = pango_layout_iter_get_line_readonly (layout_iter);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

(We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program.

Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

gint count)
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

(We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

(struct _GtkStyleClass): Remove draw_cross, draw_oval, draw_ramp, which were not implemented. * gtk/gtktextbuffer.h (struct _GtkTextBufferClass): Add insert_pixbuf signal. Rename delete_text to delete_range since it also deletes pixbufs and child anchors. This almost closes bug 40245 (still need to deal with child anchors) * gtk/gtktextbuffer.c (gtk_text_buffer_class_init): Add insert_pixbuf, change signal names as appropriate, change types of signals taking marks/tags to have the specific type, not just G_TYPE_OBJECT * gtk/gtkmain.c (gtk_get_current_event_state): Add this function; closes bug 40051 * gtk/gtkoptionmenu.c (gtk_option_menu_set_history): clean up unnecessary remove_contents() call (gtk_option_menu_class_init): add a "changed" signal, closes bug 40039 (gtk_option_menu_update_contents): emit "changed" if the active menu item changes * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): fix bad cast to GtkObject, reported by Jonas Borgstrom (gdk_pixbuf_loader_finalize): don't close the loader on finalize; we can't do stuff with side effects in finalize. Instead, spew a warning if the loader isn't closed. * gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_finalize): free colormap in here, non-X ports probably need to sync to this change * gdk/x11/gdkdrawable-x11.c (gdk_x11_set_colormap): remove assertion that colormap != NULL, you can set the colormap to NULL if you like. * Makefile.am: remove gtk-config-2.0 * configure.in: Use pkg-config to locate GLib. Remove separated-out GMODULE_LIBS, GMODULE_CFLAGS; these were not used, and the gmodule libs/cflags were in GLIB_LIBS GLIB_CFLAGS anyhow. Use pkg-config to locate Pango. Output correct Pango libs to gdk-2.0.pc.in. Fix test for FREETYPE_CONFIG (typo fix). * Makefile.am (pkgconfig_DATA): install only target-specific pc files (install-data-local): symlink gtk+-2.0.pc and gdk-2.0.pc to the X11 pc files * gtk+-2.0.pc.in (Requires): require the GDK for the current target unref from here

Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

update to reflect text widget changes. 2000-07-25 Havoc Pennington <hp@redhat.com> * gtk/testtext.c, gtk/testtextbuffer.c: update to reflect text widget changes. * gtk/gtktextview.h: To be consistent with usage of "line" throughout the API to mean "newline-terminated thingy", change MOVEMENT_LINE to be MOVEMENT_WRAPPED_LINE, and MOVEMENT_PARAGRAPH to MOVEMENT_LINE. (GtkTextView): Add flags for default editability, and whether to show the cursor. Add functions to get/set that. Add (gtk_text_view_get_iter_location): new function * gtk/gtktexttypes.h: Move GtkTextLine typedef from here to gtktextlayout.h (g_convert): Add g_convert temporarily, will go in glib in a bit * gtk/gtktexttagtable.h: include gtktexttag.h, and define GtkTextTagTableForeach instead of brokenly using GHFunc. Change gtk_text_tag_table_foreach() so it doesn't use GHFunc. * gtk/gtktexttagprivate.h: Remove GtkTextStyleValues from here, moved to public header. * gtk/gtktexttag.h: Rename the "elide" attribute of tags to "invisible", since "elide" was a bad name. (gtk_text_tag_get_priority): Added (GtkTextStyleValues): put this in public header, along with functions to use it. * gtk/gtktextmarkprivate.h: Include more headers, since we no longer include gtktextbtree.h. * gtk/gtktextmark.h: Add gtk_text_mark_ref, gtk_text_mark_unref, gtk_text_mark_deleted * gtk/gtktextlayout.h: Don't include the "really private" headers, only buffer/iter. Forward declare GtkTextLIne and GtkTextLineData to make this possible. Now we only need to install gtktextlayout.h, not gtktextbtree.h and gtktext*private.h. (However the Makefile.am isn't changed yet because of the logistics of merging gtk-hp-patches piecemeal) * gtk/gtktextiterprivate.h: include btree header, so it compiles; rename gtk_text_iter_get_line to gtk_text_iter_get_text_line since gtk_text_iter_get_line is now used in the public API for a different purpose. * gtk/gtktextiter.h: Clean up function names to be more consistent. Always call char offset "offset" and byte index "index". A "line" is always a line number. (gtk_text_iter_is_last): new function, more efficient than the existing way to check (gtk_text_iter_is_first): new function, also more efficient (gtk_text_iter_up_lines, gtk_text_iter_down_lines): Remove these (gtk_text_iter_next_char, gtk_text_iter_prev_char): Renamed from gtk_text_iter_forward_char, etc. (gtk_text_iter_forward_to_tag_toggle): Renamed from forward_find_tag_toggle, since this isn't a linear search (GtkTextCharPredicate): rename from GtkTextViewCharPredicate (gtk_text_iter_forward_search, gtk_text_iter_backward_search): New functions, search for a buffer substring. * gtk/gtktextbuffer.h: Add fields to store whether a paste is interactive and default editable (since we need to store that info until we receive the selection data). Remove all the _at_char and at_line etc. versions of functions; only have iterator versions. Add _interactive() versions of functions, that consider the editability of text. (FIXME add interactive flag to the insert/delete signals per Darin's suggestion) (gtk_text_buffer_get_tag_table): new function, demand-creates the tag table if necessary Remove declaration of gtk_text_buffer_get_iter_from_string (_gtk_text_buffer_get_btree): private/internal function, added. * gtk/gtktextbtree.h: Remove forward decl of GtkTextLineData. (gtk_text_line_is_last): new function

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction.

This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public.

Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.)

Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code.

(Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize.

Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types.

Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection.

Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine.

(Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.

printf ("Layout pars: %u lines: %u size: %d x %d Screen width: %d\n",
paragraphs, wrapped, layout->width,
layout->height, layout->screen_width);
Remove all references to offscreen flag which was no longer used. Thu Jun 1 23:05:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c: Remove all references to offscreen flag which was no longer used. * gtk/gtkprivate.h (enum): Remove unused flags and compress. * gtk/gtkframe.c (gtk_frame_set_label_widget): Check for non-null label_widget->parent. * gtk/gtkentry.c: Get rid of code to deal with PangoAttribute which no longer was used. * gdk/gdkpango.c (gdk_pango_context_get_info): make static. * gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks for null arguments. * gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add check for destroyed windows. Thu Jun 1 13:48:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmulticontext.c: Add a finalize method and unref the slave context there. * gtk/gtkinvisible.[ch]: Make reference counting behavior identical to GtkWindow. Thu Jun 1 01:54:11 2000 Owen Taylor <otaylor@redhat.com> * Makefile.am gdk/gdkpango.c: Copy the layout render function from pangox to here, so we can write them independent of rendering system, using GDK primitives. * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable, since we have a rendering-system independent implementation in terms of draw_glyphs(). * gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New function to render a single line. * gdk/x11/gdkpango.c: Move the guts of this file mostly into ../gdkpango.c, which simplifies things, since we don't have to deal with raw X gc's. Fri May 19 04:28:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add get_log_attrs() function to get the logical attributes for a given GtkTextLine. Tue May 30 16:05:39 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track g_locale_get_codeset() to g_get_codeset() change. Tue May 30 15:03:19 2000 Owen Taylor <otaylor@redhat.com> * gtk/testcalendar.c (calendar_font_selection_ok): Use font descriptions. * gtk/gtkentry.c (gtk_entry_draw_text): Center text within the entry. * gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of redoing (vastly simplifying) for Pango. Still needs quite a bit of work. (Size selection is currently poor. List of predefined sizes is not a good idea, since all of these sizes won't necessarily be distinct.) Tue May 30 13:50:19 2000 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle CODESET results for LANG=C. Mon May 29 15:49:10 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC which takes a stringized pango font description; ignore the older 'font' and 'fontset' declarations. * gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font field with a GdkFont derived via gdk_font_from_description(), for compatibility. (Should we just remove it entirely? Probably too much compatibility breakage, but people should be migrating to the new Pango stuff as quickly as possible.) Mon May 29 15:47:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/. Mon May 29 15:44:46 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcalender.c: Roughly pango-ized. Really needs redoing; there are some bugs in size allocation right now, the semi-existant distinction between header / day fonts was removed, but, with Pango, could actually be made functional in a nice way. * gtk/testcalender: Move calender from examples into this directory as a test program. (We really need to restrcture testgtk into a whole directory full of tests for every widget or functionality group, separated into multiple .c files.) Mon May 29 15:19:56 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (file_exists): Fix stupid typo that was keeping RC file from being loaded. * gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized RC file font code. Mon May 29 14:31:27 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description): Add function to load a GdkFont from a PangoFontDescription. Fri May 26 17:16:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able to have any widget for the label, use a GtkLabel widget to display the text. (Based partially on a patch from Anders Carlson.) (Quite a bit of code reorganization - strip 90% of the guts out of gtkaspectframe and add a single virtual func to GtkFrameClass - compute_child_allocation.) Fri May 26 12:00:02 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized. (Removed clist->row_center_offset field because caching it wasn't saving time or code, added private function _gtk_clist_create_cell_layout()). Wed May 24 15:59:37 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccellabel.c: Pangoized. * gtk/[hv]ruler.c: Pangoized Mon May 22 19:23:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_init): Use gtk_clist_set_column_auto_resize() to remove need need for manual column width computations. Mon May 22 18:50:26 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel, ensuring Pango correctness, and considerably simplifying the code. * gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE. * gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect getting of numbers of lines. * gtk/gtklabel.c (gtk_label_size_request): Set the requisition to the actual requested width of the lable, not to the wrap width we set. * gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h. * gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes. * gtk/gtktextview.c: Fix structure inheritance. * gtk/gtkprogressbar.c: Pangoize. Mon May 22 15:47:30 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate in a function. * gtk/gtktextlayout.c (find_display_line_above): Fixed bug with computing line tops. * gtk/gtktextview.c (changed_handler): Fix < , <= confusion. Thu May 18 18:53:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset and y_offset coordinates to do what we need now. (The offset between buffer and layout coordinates has been reintroduced, but is a bit different than before.) * gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead handle the adjustments ourselves, and scroll as necessary using the new gdk_window_scroll(). The advantage of this is that when we are incrementally revalidating, we are essentially rearranging things around the visible portion of the screen. With the old setup, the visible portion of the screen was moved around in the layout, so scrolling and redrawing to track that caused jumping of the display. Since we now control the scrolling ourselves, we can suppress this and only redraw when things actually change. Thu May 18 18:47:25 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (redisplay_mark): We need to invalidate the region not just redisplay it after-all, since we store the cursors in the LineDisplay. (Ugly interactions here between GtkLayout and GtkTextBTree here.) * gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison. Thu May 18 18:43:21 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): Added function to scroll contents of a window while keeping the window constant. Works by XCopyArea or guffaw-scrolling depending on the details of how the window is set up. (guffaw-scrolling still needs to be filled in.) Wed May 17 22:36:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget, move the debugging that was tied to a global variable to that. * gtk/gtkmarshal.list: Add NONE:INT,INT,INT * gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate validated flag, in line data instead of setting height/width to -1. This allows us to perform operations with partially invalid buffer (using the old size for invalid lines) and thus to do incremental vaidation. Keep height/width aggregates up to date when deleting text and rebalancing the tree. * gtk/gtktextbtree.[ch]: Add functions validate a line (gtk_text_btree_validate_line), and to validate up to a number of pixels (gtk_text_btree_validate). * gtk/gtktextlayout.[ch]: Add an ::invalidated signal that indicates that something is changed and a revalidation pass is needed. Change ::need_repaint to ::changed, and make it take old and new yranges instead of a rectangle. * gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move the line_data_destroy() function from gtk_text_btree_add_view() to a virtual function in GtkTextLayout * gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(), since we are handling partial repaints in a different fashion now. * gtk/gtktextbtree.[ch]: Only repaint the changed portion of the selection instead of queueing a repaint on the entire widget. * gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move get_selection_bounds() down to btree, make the function in buffer a wrapper around the btree function. * gtk/gtktextlayout.[ch]: Add functions to check if the layout is valid and to recompute either a range of pixels aroudn a line or a certain total number of pixels. * gtk/gtktextlayout.[ch]: Cache a single line display; now that we only redraw the needed portions, the hit rate for this cache is quite high. * gtk/gtktextview.[ch]: Keep track of the first paragraph on the screen so that when re-laying-out the buffer, we can keep the same place. This requires connecting to ::value_changed on the adjustments * gtk/gtktextview.[ch]: Add idle functions to revalidate the buffer after we receive an ::invalidated signal. Wed May 17 22:10:47 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper to max of allocation and layout size, not just to the layout size. * gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size): Invalidate window so it gets redrawn properly. * gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL to mean the entire window. * gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW into public header. Mon May 15 14:51:31 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_get_name): Add function to get the name of a mark. * gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function to find the paragraph from a y position. Thu May 11 12:57:20 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid nodes have width/height >= 0, not > 0. Tue May 9 21:29:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display): Add a size_only flag, so when we only need the size, we don't create useless appearance attributes. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove duplicate setting of font description. * gtk/gtkscale.c: Use PANGO_SCALE instead of 1000 Wed Apr 26 01:53:23 2000 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into EXTRA_DIST. It does not work well when the file that everything depends on is not in the tarball. Wed Apr 26 00:56:14 2000 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c: Some hacks and fixes so that it basically works when not sitting in the GTK+ build tree. 2000-05-03 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag): Properly determine the ordering of the tag root and the current line within the tree. Previous algorithm only worked if the tag root's immediate parent was the common root of both the current line and the tag root. Wed Apr 26 00:43:00 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (set_para_values): Fix some bugs in alignment. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Track the widget text directional dynamically. * gtk/gtktextview.[ch]: Added functions to get and set default wrap mode. Tue Apr 25 23:47:38 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug in cursor location computation. Tue Apr 25 23:22:59 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/ vadjusment values properly when layout gets smaller. * gtk/gtktextview.c (need_repaint_handler): Areas being passed in are far completely inaccurate, and sometimes too small, so, for now, just queue a redraw on the whole visible region. 2000-04-25 Havoc Pennington <hp@redhat.com> * gtk/gtktextbtree.c (summary_destroy): new function to destroy tag summary nodes (gtk_text_line_next_could_contain_tag): this function was totally broken if the line passed in wasn't below the tag root. Fix it. (gtk_text_btree_first_could_contain_tag): In the tag == NULL "wildcard" case, we have to do a linear scan. Blah. (gtk_text_btree_last_could_contain_tag): In tag == NULL case, we have to do the linear scan (tag_removed_cb): When a tag is removed from the tag table, remove the GtkTextTagInfo node from the btree. (gtk_text_btree_spew): Implement the spew function, for our debugging pleasure. Tue Apr 25 19:40:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix a problem with referring to the wrong buffer. * gtk/gtkentry.c: Fix focus-in/focus-out confusion. * gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default font description to gtk_style_new() - otherwise things don't work without a .gtkrc file. * gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the tags table if we create it ourself, too. * gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since it was conflicting with XKB modifiers. * gtk/gtktextview.[ch]: Add simple support for GtkIMContext. Mon Apr 24 19:34:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem with deletion from last commit. Mon Apr 24 19:29:40 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language in the context from the current locale. * gtk/gtkentry.c (gtk_entry_size_request): Use language from the context, not hardcoded value. * gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual, not logical. Sun Apr 23 23:39:18 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as attributes - that doesn't handle partial-glyph selection properly. Instead use new pango_layout_line_get_x_ranges() functionality to draw the selection. * gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x() now properly handles out-of-range coordinates. * gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved. * gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte() public. * gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext for paragraphs opposite to the base direction of the widget. * gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment. * gtk/gtktextlayout.c: Don't split segments on marks, since that causes Arabic words to reshape as you cursor through. * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual cursor position when moving vertically with the arrow keys and scrolling with page-up/page-down. (Arrow keys save only the X, scrolling saves both X and Y.) This means you can line-up / line-down or page-up / page-down without losing your place, and also that moving vertically with the cursor keys keeps the same X position, not the same character count: * gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical arrow keys move by display lines, not paragraphs. Tue Apr 18 14:16:50 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtklayout.c: Make sure that the bin window is at least as big as the allocation. (Should we also make sure that the bin window is big enough to completely cover widget->window?) * gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add function to get the onscreen rectangle. * gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account for offsets in window coordinates. Sun Apr 16 16:13:27 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset confusion. * gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction from the widget direction. * gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg): Add a "direction" attribute. * gtk/gtktextview.c: global s/tkxt/text_view/. * gtk/testtext.c: Added long block of text in Arabic, to test out the direction attributes. (Some problems with the shaping system for arabic become obvious - like the fact the cursor splits words into unjoined pieces.) Fri Apr 14 12:54:34 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextdisplay.c (render_layout): Add overstrike handling. * gtk/gtktextlayout.c: Fix up alignment. * gtk/testtext.c: Add some tests for centering, wrapping. Fri Apr 14 09:26:22 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs(). If we wrote GTK+-specific layout-render function this could just replace the draw_layout() operation in the vtable. * gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to pango_layout_get_cursor_pos() and use that function. * gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it is a non-static symbol. * gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y() with gtk_text_btree_find_line_by_y() * gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout renderer that handles GtkTextAppearance attributes. * gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h: - Move the values in the style that don't affect geometry into a GtkTextAppearance structure. - Change underline to take a PangoUnderline and "font" a string representation of a font description - Add a "font_desc" attribute which takes a FontDescription structure. * gtk/gtktextlayout.[ch]: - Get rid of the display-line list per each line. Instead, we generate, on demand, a GtkTextLineDisplay structure which] contains a PangoLayout * and other necesary information (offsets, cursor locations) for displaying a paragraph. - Get rid of the code to wrap lines, create display chunks, etc. Instead, we just go through a paragraph and convert it into the necessary inputs to a PangoLayout. - Implement a new attribute type, GtkTextAttrAppearance. This holds a GtkTextAppearance, and is used to pass colors, stipple, etc, through from the layout to the display without having to use lots and lots of individual attributes. - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos() in terms of PangoLayout functions. * gtk/gtktextview.c: - Handle passing the necessary PangoContext to the layout - Some fixups in painting to deal with the automatic backing store and offsetting of GTK+-1.4 - Add a style_set handler so that the default style reacts properly to theme changes. * gtk/gtktext?*.[ch]: Random code-style fixes. * gtk/testtext.c: Substitute in languages that Pango handles now for Thai Mon Apr 10 10:33:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget, in original form preparatory to Pango-ization and gdkimcontext-ization. Thu Apr 6 19:25:39 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.c: Move default implementations to real_* vfuncs, so that we can derive from gtkimcontext in language bindings properly. Thu Apr 6 16:02:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval. Add a compose table including (almost) all the compose combinations from X. This is 6k of static, shared data as opposed to 50k or so of dynamic data in the XIM implementation. * gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval): Moved functions to convert keyvalues from and to unicode here from the win32 port and made them public. Wed Apr 5 16:37:29 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1. Wed Apr 5 16:27:45 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext.[ch]: Base class for new input context system * gtk/gtkimmulticontext.[ch]: Proxy input context that allows the real input context implementation to be loaded from modules and switched on the fly. * gtk/gtkcontextsimple.[ch]: Simple implementation of an input context that just does direct keysymbol => unicode translation. * gtk/gtkentry.[ch]: Start switching editing over to using GtkInputContext. (No handling of preedit yet.) Wed Apr 5 15:48:41 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too many substitutions. (klass should not be subsituted.) Wed Apr 5 00:18:14 2000 Owen Taylor <otaylor@redhat.com> * configure.in: Add checks for Pango * configure.in docs/Makefile.am: Add test for sgml2html and allow 'make dist' without building html, but print out warnings in that case. (For making snapshots) * gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am: Add Pango libraries and C flags * gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c: Add function (gdk_draw_layout) to draw a pango layout. * gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions for getting Pango contexts for GDK. * gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set() * gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional editing. * gtk/gtkentry.c: Hack in simple Hebrew input with direct keysym => unicode translations. More languages can be added here, but real input-method support is needed. * docs/Changes-1.4.txt: Added note about entry behavior. * gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions to set the reading direction for a widget and the global direction. Add test which allows toggling the global direction. Two private flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR) * gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c * gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango * gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking, underlining now handled by Pango. * gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription to RCStyle and Style. (Having both this and the old font name and GdkFont is temporary.) * gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added convenience functions for creating contexts and layouts for widgets. * gtk/testgtk.c: Enhance label tests with multilingual labels.
